  • Patent number: 10897411
    Abstract: A method of performing passive packet cross-checking of flooding packets within a multi-node system is disclosed. A first flooding packet is transmitted from a communication node to a first additional communication node of the multi-node system. The first flooding packet causes the first additional communication node to transmit a second flooding packet based on the first flooding packet to the communication node and to a second additional communication node of the multi-node system. A copy of the first flooding packet is stored in a memory cache of the communication node. The second flooding packet is received at the communication node from the first additional communication node. The second flooding packet and the stored copy of the first flooding packet are compared at the communication node, and a status of the first additional communication node is determined based on the comparison.

  • Patent number: 10897652
    Abstract: Embodiments of the inventive concepts disclosed herein are directed to systems and methods of providing in-flight entertainment related content. A content server may upload first content to in-seat client terminals for local storage and subsequent playback. The content server may upload second content to overhead client terminals for local storage and subsequent playback. Each client terminal may synchronize to a defined reference point for initiating playback of the first content and of the second content. Each client terminal may operate independently of each other and the content server subsequent to initiation of the playback. Subsequent to the initiation of the playback and in response to a system disruption to the playback at a client terminal, the client terminal may resume the playback of the corresponding content at the client terminal at a point at which the disruption occurred. The resumption may be independent of the playback in other client terminals.

  • Patent number: 10896489
    Abstract: Systems and methods for improving target object visibility in captured images can include an imaging sensor for mounting on an aircraft at a fixed position and orientation. A predetermined portion of the aircraft can appear as a region of interest (ROI) at a predefined location across images captured by the imaging sensor. A processor can receive a first image signal captured by the imaging sensor and corresponding to a first image that includes the ROI. The processor can determine a first image intensity range of the ROI in the first image and gain and offset values for modifying the first image or a subsequent image. The processor can cause a second image signal, received from the imaging sensor, to be amplified according to the gain and offset values and cause the region of interest in a second image to have a second image intensity range different from the first image intensity range.

  • Patent number: 10894595
    Abstract: A redundant mechanical control system incorporates a jam override subsystem to enable a breakout or break-away feature of the redundant mechanical control system. The jam override subsystem includes a spring and detent system to apply an axial force to a portion of an interconnect. The interconnect mechanically links a first portion of the redundant mechanical control system with a second portion. When a failure occurs, rendering inoperable the first portion or the second portion of the redundant mechanical control system, the axial force of the spring and detent system is overridden by a compression or extension force of the operable portion of the redundant mechanical control system.

  • Patent number: 10887255
    Abstract: A system and method for Controller Pilot Data Link Communication (CPDLC) chat is disclosed. The system receives CPDLC signals and displays CPDLC messages sent and received from both ownship aircraft and optionally other nearby aircraft on the ownship aircraft display. Not to interfere with a traditional CPDLC display, the system is an additional display of all CPDLC data and highlights messages to and from the ownship on the aircraft display. The system allows a declutter option to limit displayed data to that of a current data authority (CDA) as well as a limit in range, geography, altitude, aircraft type, etc.

  • Patent number: 10882617
    Abstract: A system and method for passenger interaction receives an input from a passenger to create an actual, virtual reality (VR) or augmented reality (AR) environment within which the passenger wishes to immerse and then share via social media. The input includes a passenger order to immediately share the environment, delay sending or store the environment. Each environment includes a characteristic of the passenger as immersed within a location element and vehicle element associated with the vehicle in which the passenger is traveling. The system maintains a hardware suite capable of creation of the desired environment and displaying the environment to the passenger.

  • Patent number: 10873429
    Abstract: A method of performing data frame error recovery is disclosed. A data packet is received and tested to determine whether the data packet includes one or more bit errors. The data packet is compared with one or more data packets stored in a recovery buffer to identify a duplicate of the data packet when the data packet includes one or more bit errors. One or more bits affected by the one or more bit errors are identified based on a comparison between the data packet and the duplicate of the data packet. Different combinations of bit values for the one or more bits are determined, and the data packet is tested with the different combinations to identify a correct combination of bit values for the one or more bits. The data packet is recovered based on the correct combination of bit values for the one or more bits.

  • Patent number: 10864997
    Abstract: An integrated aircraft lighting and display panel includes high-density arrays of micro-scale light-emitting diodes (LED) set into a flexible printed circuit board (PCB). The PCB and LED arrays may be set into structural layers corresponding to overhead panels, side panels, bin panels, divider panels, doorway panels, or other interior structural panels of the aircraft. The LED arrays may be activated by a controller to provide cabin lighting, indicate aircraft signage, display high-resolution image or video graphics, or any simultaneous combination of all three. The panel may have a translucent or transparent decorative outer skin which may mimic the outward appearance of wood, stone, bamboo, or other decorative materials while the integrated lighting and display panels are inactive. Highly reflective core materials, such as an aluminum core in a honeycomb pattern, may guide the luminous output of the LED arrays through the outer skin.
